    Gs1100 swap

    Hello, I have a 1981 gs750e that just this past Monday gave up the ghost. I did some digging and it appears the crankshaft is sheared in half. With that being said, how difficult is it to swap q tscc gs1100 into my existing frame? What should I look for in purchasing one? Can i swap my gs750 head onto the gs1100 block? Any info would be appreciated. Thanks

    Bolt in the 1100 engine and never look back. 750 head is too small for the 1100.

      With that being said, are the cams not the same size? What should I look for in a used engine other than chain drive and it not looking rough?

        Why would you want to bolt on a 750 head? Find another 750 motor or start to find out what issues come up with doing the 7/11 swap

          Because my head has web cams in it.

            Something tells me that a stock 1100 <might> out-perform a 750 with Web cams.

              My thinking was that perhaps I could put my web cams in the 1100 head...

                I'd be surprised if the bore center spacing on the two engines is the same, which would be necessary if that's going to work.

                  750 cams will work in the 1100.
